The purpose of this prospective study was to define the enhancement pattern of the facial nerve in idiopathic facial paralysis (Bell's palsy) on magnetic resonance (MR) imaging with routine doses of gadolinium-DTPA (0.1 mmol/kg). Using 0.5T imager, 24 patients were examined with a mean interval time of 13.7 days between the onset of symptoms and the MR examination. Contralateral asymptomatic facial nerves constituted the control group and five of the normal facial nerves (20.8%) showed enhancement confined to the geniculate ganglion. Hence, contrast enhancement limited to the geniculate ganglion in the abnormal facial nerve (3 of 24) was referred to as equivocal. Not encountered in any of the normal facial nerves, enhancement of other segments alone or associated with geniculate ganglion enhancement was considered to be abnormal and noted in 70.8% of the symptomatic facial nerves. The most frequently enhancing segments were the geniculate ganglion and the distal intracanalicular segment.
本前瞻性研究的目的是利用常规剂量的钆喷酸葡胺（0.1 mmol/kg），通过磁共振（MR）成像确定特发性面神经麻痹（贝尔麻痹）患者面神经的强化模式。使用0.5T成像仪，对24例患者进行了检查，症状出现至MR检查的平均间隔时间为13.7天。对侧无症状面神经作为对照组，5条正常面神经（20.8%）显示强化仅限于膝状神经节。因此，异常面神经中强化仅限于膝状神经节的情况（24例中有3例）被称为可疑。正常面神经中均未出现仅其他节段强化或伴有膝状神经节强化的情况，这种情况被认为是异常的，在70.8%的有症状面神经中被观察到。最常出现强化的节段是膝状神经节和颅内段远端。
